Signature Detail

SMB: Samba NetDFS Overflow

This signature detects attempts to exploit a known vulnerability in the Samba NetDFS RPC netdfs_io_dfs_EnumInfo_d Handler. A successful attack can lead to a buffer overflow and arbitrary remote code execution within the context of the server.

Extended Description

Samba is prone to a remote heap-based buffer-overflow vulnerability because it fails to properly bounds-check user-supplied data before copying it to an insufficiently sized memory buffer. An attacker can exploit this issue to execute arbitrary code with superuser privileges, facilitating the complete remote compromise of affected computers. Failed exploit attempts will result in a denial of service. This issue affects Samba 3.0.25rc3 and prior versions.
